Abstract: An image decoding method that decodes bit streams including encoded signals for images each of which have been divided into a plurality of slices including a plurality of encoding units and encoded, said method including a decoding step in which the encoded signals are decoded. Each of the plurality of slices is either a normal slice having information included in the slice header therefor that is used in a different slice or a dependent slice for which information included in the slice header of a different slice is used for decoding. Each of the images includes a plurality of rows including a plurality of encoding units and if a normal slice starts from other than at the beginning of the first row, a second row after the first row does not start from a dependent slice.

Abstract: Un método de decodificación de imágenes capaz de reducir la carga de procesamiento incluye: obtener un indicador de control de límite para controlar conjuntamente una operación de filtro de desbloqueo y una operación de compensación adaptable de muestra para un límite de corte de un corte actual que es decodificado que está incluido en una representación visual codificada (S11); decodificar el corte actual (S12); realizar la operación de filtro de desbloqueo basada en el indicador de control de límite únicamente sobre por lo menos uno de un límite de corte superior o un límite de corte izquierdo de entre todos los límites de corte del corte actual que ha sido decodificado (S13); y realizar la operación de compensación adaptable de muestra dependiente del indicador de control de límite únicamente sobre por lo menos uno del límite de corte superior o el límite de corte izquierdo de entre todos los límites de corte del corte actual que ha sido decodificado (S14).

Abstract: An image encoding method for an image comprising a first row and a second row of largest coding units (LCUs), the first row comprising three or more LCUs and further comprising a normal slice and a group of one or more dependent slices is provided. The method comprises partitioning the image, upon determining that wavefront parallel processing is enabled and that the first LCU of the at least one or more LCUs of the normal slice is not the first LCU in the first row, so as to ensure that a last LCU of the at least one or more LCUs of the group of one or more dependent slices is arranged on the first row.

Abstract: An image decoding method capable of reducing processing load includes: obtaining a boundary control flag for jointly controlling a deblocking filter operation and a sample adaptive offset operation for a slice boundary of a current slice to be decoded included in a coded picture (S11); decoding the current slice (S12); performing the deblocking filter operation based on the boundary control flag only on at least one of a top slice boundary or a left slice boundary among all slice boundaries of the current slice that has been decoded (S13); and performing the sample adaptive offset operation dependent on the boundary control flag only on the at least one of the top slice boundary or the left slice boundary among all the slice boundaries of the current slice that has been decoded (S14).

Abstract: Una indicación de dependencia se señala dentro del comienzo de un paquete, es decir, en la cercanía de un encabezado de corte que es analizado o un conjunto de parámetros. Esto se logra, por ejemplo, al incluir la indicación de dependencia al comienzo del encabezado de corte, preferiblemente después de un elemento de sintaxis que identifica el conjunto de parámetros y antes de la dirección de corte, al incluir la indicación de dependencia antes de la dirección de corte, al proporcionar la indicación de dependencia a un encabezado de NALU utilizando un mensaje separado o mediante el uso de un tipo de NALU especial para NALUs que llevan cortes dependientes.

Abstract: An image decoding method that decodes bit streams including encoded signals for an image that has been divided into a plurality of tiles as well as divided into a plurality of slices, and encoded, said method including a decoding step in which the encoded signals are decoded. Each of the plurality of slices is either a normal slice having information included in the slice header therefor that is used in a different slice or a dependent slice for which information included in the slice header of a different slice is used for decoding. If a normal slice starts from other than at the beginning of the first tile, a second tile encoded after said first tile does not start from a dependent slice.

Abstract: A dependency indication is included at the beginning of a packet, i.e., in the vicinity of an analysis target slice header or parameter set, and is delivered by a signal. This is achieved, for example, by including the dependency indication at the beginning of the slice header, ideally after a syntax element identifying the parameter set, and before the slice address, by using a separate message and providing the dependency indication to an NALU header, or by using a special NALU type used in an NALU holding a dependent slice.

Abstract: An image decoding method for decoding a bitstream including a coded signal resulting from coding tiles and slices into which an image is partitioned, the method including decoding the coded signal, wherein each of the slices is either a normal slice having, in a header, information used for an other slice or a dependent slice which is decoded using information included in a slice header of another slice, and when the normal slice starts from a position other than a beginning of a first tile, a second tile coded next to the first tile does not start from the dependent slice.
